A year and a half ago my muffler pipe rusted through and broke just before the flange leading to the resonator. Thanks to some excellent instructions on this forum I was able to fix it with an FX pipe kit. Apparently this is a pretty common spot for the pipe to break.
I was quite happy with the result...until a couple days ago when I started up my car and heard the old VROOOM! And sure enough, the replacement bit of pipe had broken in exactly the same spot. See pic below. (The clamp is on the muffler side of the pipe just before it connects to the resonator.)
I was hoping this repair would last more than a year and a half. I could replace the muffler but I don't think there's anything wrong with it. So I think I'm just gonna do the same fix but I'd like it to last longer if possible. This is the pipe kit I used. Does anyone know of a way to extend its useful life? Something I can spray / paint to protect against rust? I've also looked around for comparable products from other companies but it seems this is the only one that will fit the Civic.
Also, wondering if anyone has any tips for getting the old piece of pipe kit off the muffler pipe. I figure it will be rusted on pretty good and I don't want to damage the pipe itself. I'll heat it up with a torch first. Is there a tool that can grab a pipe without making a dent? Or maybe I'm overthinking this. Any advice would be appreciated.
Hi,
THe fx1748 kit is mild steel.
To answer the previous helper the welding people you cant weld SS T304 OEM exhaust to Mild Steel.
Your original exhaust from Honda is Stainless Steel T304 .
I also ran into this and the FX1748 rusted in one winter to completely brake off.
The company closed and ran so it wont offer warranty.
The fix is SS same type kit .
After long search I found one.
Bear River Converter sells SS parts that can work.
BRC8175SS joint
BC175SS Stainless high quality clamp.
These parts only cost 10-15 dollar more than that FX1748 cheap mild steel crap.
If I knew this a year ago, I would not be dong the job twice.
These parts are T304 Stainless Steel like the OEM exhaust. NOTE:
1) The exhaust gasket on the new kit 1/8 bigger on that kit so I just used JB weld high temp to close the gap.
Worked well.
Or you can just buy exhaust donut Honda OEM. It will be exact fit.
2) I reused Hondas Spring bolts since the nut I didn't have to break off the other side from the resonator.
The kit comes with SAE Standard bolts not metric. You can do it both ways.
3) this repair T304 SS will last as original exhaust close to 10 yr
I haven't been on the forum in ages.. Where Is EZONE.. Is he alive?
Someone should sticky this repair and rewrite it .. It makes you keep your high quality muffler OEM ..
The **** the muffler shops sell now is not T304 Stainless Steel. Wont last 1-2 years in the Snow belt.
Keep your original OEM muffle and dont do this job twice with cheap mild steel **** FX kit.
Or get a Monroe Muffler cheap mild steel muffler.
